We give users access to local disk space on nodes (spinning disk for older<br>
nodes, SSD for newer nodes), which (for the most part) GE will address with<br>
the $TMPDIR job environment variable. We have a "ssd" boolean complex that<br>
users can place in their job to request SSD nodes if they know they will<br>
benefit from them.<br>
<br>
We also have labs that use non-backed up portions of their network storage<br>
(Isilon for the older storage, DDN/GPFS for the newer) for scratch space<br>
for processing of pipeline data, where different stages of the pipeline run<br>
on different nodes.<br>
